Bad valve - Worked well first year. Next year the valve would not shut off water and allowed for unwanted slow and steady stream. Also, it tends to freeze up if you play with the buttons too much. The remedy is to take out the batteries for a few minutes.
Very good product - The Gilmour Electric Water Timer is a quick and easy way to get your watering on a regular schedule. I had invested a significant amount of money and effort in soaker hoses and needed a way to regularly water my vegetable garden without forgetting to turn the water off each time! I have this water timer setup to water every 12 hours (morning and evening) for 20 minutes. It works great.
Battery cover leaks - I purchased 4 of these last year and only one is functional this year. The problem is the battery cover leaks water in which ruins the timer. Also, the start button is really difficult to push. I m trying a different model this year.
Disappointed - I ordered three of the 9100 s the first week of June, 2008. I was surprised that one of the units had completely stopped working by the second week of July and then a week later a second unit failed. Replacing the batteries did not help with either of the failed units so I will be returning all three units for a refund. The refund will only be a partial refund since it has been over 30 days since I made the purchase.
OK - Works as advertised. Just kinda basic. It goes on and off, but few programmable features. OK for the price, though.
